Effect of cholesterol in artificial diets for Mediterranean prawns
Mediterranean prawn (Penaeus kerathurus Forsskal) postlarvae (2 months old) were fed ad libitum with previously tested artificial diet (41% D.W., mainly of vegetal origin) supplemented with different percentages of cholesterol (0, 0.1, 0.5, 1.0 and 3.0%) and fresh bivalve mussel. Growth and survival rates were determined twice. Considering supplemented formulas only, data show that: (a) individual weights were higher with 0.1% cholesterol in the diet; (b) survival sharply dropped in the last week of the experiment, in particular with 0.1 and 3.0% cholesterol diets; and (c) with 1.0% cholesterol, mortality and growth counterbalanced giving over-all better results. No artificial feed can compete with the natural diet, either for survival rate or for individual growth.
